Some great examples of Halloween fog. For those who might not know, fog can be run through tubes or containers of ice to chill the fog to make it dense and heavy, and clingy. A windy night will kill the effect, but it sure looks great. I owned a fog machine for a couple of years before I learned about this neat technique.

The one I used was a trash can chiller. The tube winds through a plastic trash can filled with ice. It was difficult to hide and position, so I started using a plastic tube with ice packs inside...but I'm not really sure which is the best.

Yeah, I've seen about 20 different designs just for cooler fog chillers. I've also seen the one that you're talking about. That's one of the hardest things, I think, about haunting. Making mistakes or even worse being afraid to. Trial and error.

What about putting ice in a fogger itself? Would that create more fog, or is that just an excercise in futility? Forgive my ignorance on this topic. All I know is that I bought a fogger last year, and I was incredibly disappointed with the results.

I'm not sure if that's something that's possible. My very crude understanding is that the glycerin fog juice is getting vaporized by the heat of the machine so ice would probably alter that process.

I was really pleased with the tubing method (I didn't have to build anything). I just pointed the nose of the fog machine into the tube and the ice packs and thin ice bottles did the job pretty well.

A while back I posted a youtube link to a guy's fog going through some irrigation tubing and he claimed that he didn't even use ice. So maybe the act of the fog having some time away from the heat source as it travels through the tubing causes it to get dense.

Ahhhh, makes sense! The fact that it isn't dispersing, but has time to cool would cause it to get denser as it moved through the tubing! Ice would accelerate this process....wow! Thanks Rot! I'll have to do some experimenting in the next few days!!!
